PURPOSE:To provide a resin compsn. for inflation film, which gives a film having improved optical properties and blocking resistance, by mixing an ethylene/ alpha-olefin copolymer with polyethylene prepd. by high-pressure radical polymn. CONSTITUTION:85-93wt% ethylene/C3-C18 alpha-olefin copolymer having a density of 0.895-0.935 and a melt index of 0.1-5g/10min is mixed with 15-7wt% polyethylene having a molecular weight dissociation degree index (SM value) of at least 6 and a melt index of at least 0.1 prepd. by high-pressure radical polymn. Preferred ethylene/alpha-olefin copolymer resin includes those having a density of 0.895-0.935, particularly 0.915-0.925 and a melt index of 0.5-2g/10min.
